Application filed March A, 1915. Serial No. 12,092.

To all whom it may concern;

Be it known that I, WALLACE B. MoALLIs,

Tire, a citizen of the United States, and a resident of Camden, county of Camden, State of New Jersey, have invented certain Improvements in Sash-Retainers, of which the following is a specification.

The object of my invention is to provide means for retaining a window sash in any position. to which it is adjusted and to so arrange the device that while the sash can be forced up under pressure, it will be locked against downward movement.

In the accompanying drawings :Figure 1 is a sectional view through a car window sash illustrating my invention; Fig. 2, is a side view of suflicient of a car window sash and frame to show an exterior view of my improved retainer; Fig. 3 is a sectional plan view on the line aca Fig. 2, drawn to an enlarged scale; Fig. 4 is an edge View of the retainer; Fig. 5 is aperspective view looking at the face of theretainer; Fig. 6 is a perspective view looking at the interior of the retainer; and Figs. 7 and 8 are views showing the two positions of the retaining lever.

While I have illustrated my invention as applied to a car window sash, it will be understood at the outset that the device can be applied to any window sash which has to be retained in position by a fastening device.

1 is the frame.

2 is the sash arranged to slide in the frame.

3 is the fastening device, consisting of a plate 4 bent, as shown in Fig. 5 in the present instance, to form an end guiding section 5, and a thumb hold 6. The sash is cut out sufliciently to allow the moving elements of the retainer to work freely therein.

7 is a lever pivoted at 8 and the one end of this lever extends through a slot 5 in the portion 5 of the plate, and the opposite end of the lever is attached to a latch operating slide 9 on the outside of the plate 1, by means of a rivet or pin 10 which passes through a slot 11 in the plate. Projecting from the lever? is a pin 12, and 13 is a spring bearing upon the pivot 8 and having a hooked portion which engages the pin 12 at one end, and another hooked portion engaging a pin 1%, projecting from the plate 4, so that the tendency of the spring is to keep the lever in its lifted position.

SASH-RETAINER.

Patented Oct. 5,1915.

1 Oil .One end of the lever -7-is a head beveledas shown in Fig. 3, and projecting into the VV-shaped space formed by the flanges 16 of a plate 17, which is slotted for the passage of the. lever and has a certain amount of free longitudinal movement. To

the wall of the groove 18 of the frame 1 is secured a V-shaped rail 19, which enters the spaces between the beveled head 15 of the lever 7 and the flanges 16 of the plate 17, as clearly shown in Fig. 3. The rail can be secured in position by a series of screws, or other suitable fastenings. The lever and its head are normally in the position illustrated in Fig. 7, and consequently the head binds at the rear upon the plate 17, and at its lower forward end against the V-shaped rail 19, clamping the rail tightly against the flanges 16 of the plate 17. The parts are thus held with such rigidity as to retain the sash in position and prevent it from accidentally moving. When it is desired to move .the sash either up o-rdown the thumb hold 6 and the lip 9 on the'slide 9 are drawn together by the action of the thumb and first finger, which will move the lever into the position shown in Fig. 8. Thus the sash is free and can be moved to any position. i

I claim:

1. The combination in means for retaining a sash in a fixed position, of a V-shaped rail mounted in a groove on the frame in which the sash slides, a retainer mounted on the sash consisting of a plate, a lever pivoted thereto having a head, and a loose plate having flanges extending back of the V- shaped rail, the head being in front of the rail so that when the parts are in the normal position the rail is clamped between the head and the flanges of the plate, and when the head is released the rail is free and the sash can be raised or lowered.

2. Thecombination of a frame having a groove therein, a V-shaped rail mounted in the groove, a sash arranged to travel in the groove, a retainer carried by the sash consisting of a plate, a lever pivoted to the'pl'ate frame, of a groove therein, a V-shaped rail mounted in the groove, a sash arranged to travel in the groove, a retainer consisting of a plate having a right-angled extension located at the edge of the sash, said extension being slotted, a lever pivoted to the plate and extending through the said slot, and having a beveled head'thereon projecting into the groove of the rail, a slotted plate mounted between the head and the end of the retainer plate and having beveled flanges extending back of the rail, a spring tending to hold the lever in its raised position so as to cause the head to clamp the rail against the flanges of the plate, and means for moving the lever against :the pressure of the spring.

4-. The combination of a frame, a sash arranged to slide therein, a vertical rail, a retainer on the sash, the retainer on the sash having a headed lever arranged to bear on one side of the rail, and a loose plate carried by the retainer and having flanges bearing upon the opposite side of the rail, with means for yieldingly holding the parts in the locked position.

In testimony whereof, I have signed my name to this specification, in the presence of two subsorib ing Witnesses.
